Waterproof flame-retardant wood hardening agent and preparation method thereof

Abstract

The invention discloses a waterproof and flame-retardant wood hardener, which is prepared from the following raw materials in parts by weight: 5-10 parts by weight of water glass, 5-10 parts of borax, 10-15 parts of magnesium sulfate, 2-3 parts of guar gum, and Ammonium sulfate 0.1-0.2, titanate coupling agent 0.1-0.2, styrene 2-4, methyl methacrylate 4-6, sodium lignosulfonate 0.5-1, sodium carboxymethylcellulose 1-2, Modification additive 5-10, water 80-100. The wood hardening agent of the present invention has the characteristics of good permeability, strong binding force with wood, not easy to be lost, good durability, good hardening effect, green and environmental protection, and also has the effect of waterproof and flame retardant, and can improve the use safety and durability of wood , with high practical value.

Description

technical field [0001] The invention relates to the technical field of wood treatment agents, in particular to a waterproof and flame-retardant wood hardener and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of my country's economy, furniture, building materials, decoration and other fields have grown stronger and stronger, and the demand for wood, especially high-quality hard wood, has gradually increased, and there has even been a shortage of supply. Fast-growing tree species such as masson pine, fir, and poplar have the advantages of rapid growth and low price, and can be used instead of natural wood. They not only have good economic benefits, but also reduce the felling of natural forest trees and protect the natural environment. However, the wood of these fast-growing tree species is light and soft, and its performance is generally poor, and its application range is limited. In order to meet the needs of providin...

AI Technical Summary

Problems solved by technology

However, the wood of these fast-growing tree species is light and soft, and its performance is generally poor, and its application range is limited. In order to meet the needs of providing high-quality wood faster and better, it is necessary to harden it to increase hardness and improve performance. , to expand the use of wood

Currently commonly used resin-based wood hardeners are difficult to degrade in the environment, and contain certain free harmful substances, which pose potential hazards to human health

Non-resin wood hardeners have the problems of poor permeability, low binding force with wood, easy loss and poor durability
